Do not walk arrogantly on the earth

And walk not on the earth with conceit and arrogance. Verily, you can neither rend nor penetrate the earth, nor can you attain a stature like the mountains in height.

[Qur'aan 17:37]

Ibn 'Umar reported that the Prophet (sallallaahu alayhi wa sallam) said, "If anyone behaves insolently or walks with arrogance, he will meet Allah Almighty covered with His anger."
